This station opened on June 25, 1888, when the Union Elevated Railroad (leased to the
Brooklyn Elevated Railroad) extended its
elevated line above Broadway from
Gates Avenue northwest to
Driggs Avenue in
Williamsburg. This was a branch of the existing
Lexington Avenue Elevated, which then ended at
Van Siclen Avenue; Broadway trains ran between Driggs and Van Siclen Avenues. The Broadway Elevated was extended to
Broadway Ferry on July 14, 1888. Upon the opening of the
Williamsburg Bridge tracks in 1908, trains were rerouted across the bridge west of Marcy Avenue. The
Dual Contracts expansion projects radically changed operations at Marcy Avenue. A third track was added, allowing trains to run express, although the track remains as a stub-end at Marcy Avenue for storage and turn-arounds. The Contracts also provided for the merger of the Jamaica Line from Broadway Junction to 168th Street with the Broadway Elevated, in turn making the Broadway Elevated part of the Jamaica Line and giving trains three eastern terminals (
168th Street,
Canarsie–Rockaway Parkway, and
Middle Village–Metropolitan Avenue). On April 13, 1954, the enlarged station platform at Marcy Avenue was opened, as well as the expanded stairway facilities. In 1982, the
Urban Mass Transportation Administration gave a $66 million grant to the New York City Transit Authority. Part of the grant was to be used for the renovation of several subway stations, including Marcy Avenue. In 2002, the
Metropolitan Transportation Authority announced that elevators would be installed at the Marcy Avenue station. As part of the 2015–2019 Metropolitan Transportation Authority's Capital Program, station capacity enhancements will be made at the station. The project will assess the feasibility of widening and reconstructing the stairs at Havemeyer Street, widening the westerly outbound platform, and widening the platform level fare control areas to fit in an additional low-level turnstile. Design work started in April 2017 and will be finished in December 2017, with construction set to begin in April 2018. In December 2021, the MTA awarded a contract for the replacement of the Marcy Avenue station's elevators, to be completed by late 2023 or early 2024. == Station layout ==
